This playstyle is a supercharged version of two key full alt, which trades even more mental strain for additional speed and stamina. We aim to push the boundaries of raw speed as well as technical tapping.
Using four keys is easier said than done, because the game only has two independent inputs. Binding two keys to the same input means we need to lift one of them before pressing the other. However this problem can be overcome with enough practice.
